Aere Network public source. Everything here can be checked against the live chain (chain id 2800, https://rpc.aere.network). Scope note, stated up front rather than buried: consensus on chain 2800 is classical secp256k1 ECDSA QBFT. The post-quantum work in this repository is at the signature, precompile, account and transport layers. Nothing here makes the consensus post-quantum, and no document in it should be read as claiming so.
